Download Jupyter Notebook Mac and Start Your Python Programming Journey

In this blog, we'll walk through how to get Jupyter functional on your M1 computer -- starting with the download step and ending with a fully operational Jupyter notebook. (We'll assume you don't know if you have Jupyter on your computer yet. If you know with certainty that you have Jupyter downloaded, you can skip down here.)

Step 4: You can install Python by going to XCode Command Line Tools. You'll need to login with your Apple ID and follow the instructions. Note that the normal Anaconda download won't work here, as the M1 computer isn't 64-bit. Once you're done, head back up to Step 3.

Step 5: If you've installed Python but had trouble installing Jupyter, then go to your Terminal and type pip3 install jupyter. If that doesn't work, then head here and follow the instructions.

Step 6: In your Terminal, type jupyter notebook and hit Return. Once you do, then click "New" (on the right-hand side) and open up a Python 3 notebook.

Step 8: If you've followed the above steps, you should be good to go. I usually quit the Terminal (hold Command and press Q) because I think that, sometimes, updates won't immediately take effect without restarting the Terminal. Make sure that it works by returning to step 6 and writing commands in your Jupyter notebook.

Jupyter (formerly IPython Notebook) is an open-source project that lets you easily combine Markdown text and executable Python source code on one canvas called a notebook. Visual Studio Code supports working with Jupyter Notebooks natively, and through Python code files. This topic covers the native support available for Jupyter Notebooks and demonstrates how to:

When getting started with Notebooks, you'll want to make sure that you are working in a trusted workspace. Harmful code can be embedded in notebooks and the Workspace Trust feature allows you to indicate which folders and their contents should allow or restrict automatic code execution.

Moving cells up or down within a notebook can be accomplished via dragging and dropping. For code cells, the drag and drop area is to the left of the cell editor as indicated below. For rendered Markdown cells, you may click anywhere to drag and drop cells.

Within a Python Notebook, it's possible to view, inspect, sort, and filter the variables within your current Jupyter session. By selecting the Variables icon in the main toolbar after running code and cells, you'll see a list of the current variables, which will automatically update as variables are used in code. The variables pane will open at the bottom of the notebook.

Under the hood, Jupyter Notebooks are JSON files. The segments in a JSON file are rendered as cells that are comprised of three components: input, output, and metadata. Comparing changes made in a notebook using lined-based diffing is difficult and hard to parse. The rich diffing editor for notebooks allows you to easily see changes for each component of a cell.

You can search kbstyle(Ctrl/Cmd + F) through an entire notebook or you can search parts of your notebook by filtering your search options. When searching through your notebook, click on the Filter option (funnel icon) to search across:

Note: For added security, Microsoft recommends configuring your Jupyter server with security precautions such as SSL and token support. This helps ensure that requests sent to the Jupyter server are authenticated and connections to the remote server are encrypted. For guidance about securing a notebook server, refer to the Jupyter documentation.

Python is already installed on MAC and Linux machines. To overcome the issue of outdated and/or multiple versions of python, we will use anaconda to install python version 3.x, and to run jupyter notebooks (explained later).

Jupyter notebook is a web application to create and share documents. A notebook document can contain code, text, equations and/or visualizations. You can use jupyter notebook to write, execute and document python code. Though there are multiple ways to install and run jupyter notebook, Anaconda is the preferred way to run jupyter. After installing anaconda (version 3.x), you can follow the steps below to start jupyter notebook.

Fundamentally the problem is usually rooted in the fact that the Jupyter kernels are disconnected from Jupyter's shell; in other words, the installer points to a different Python version than is being used in the notebook.In the simplest contexts this issue does not arise, but when it does, debugging the problem requires knowledge of the intricacies of the operating system, the intricacies of Python package installation, and the intricacies of Jupyter itself.In other words, the Jupyter notebook, like all abstractions, is leaky.

Second, I'll dive into some of the background of exactly what the Jupyter notebook abstraction is doing, how it interacts with the complexities of the operating system, and how you can think about where the "leaks" are, and thus better understand what's happening when things stop working.

For various reasons that I'll outline more fully below, this will not generally work if you want to use these installed packages from the current notebook, though it may work in the simplest cases.

That bit of extra boiler-plate makes certain that you are running the pip version associated with the current Python kernel, so that the installed packages can be used in the current notebook.This is related to the fact that, even setting Jupyter notebooks aside, it's better to install packages using

When you're using the terminal and type a command like python, jupyter, ipython, pip, conda, etc., your operating system contains a well-defined mechanism to find the executable file the name refers to.

(Parenthetical note: why is the first entry of $PATH repeated twice here? Because every time you launch jupyter notebook, Jupyter prepends the location of the jupyter executable to the beginning of the $PATH. In this case, the location was already at the beginning of the path, and the result is that the entry is duplicated. Duplicate entries add clutter, but cause no harm).

A Jupyter kernel is a set of files that point Jupyter to some means of executing code within the notebook.For Python kernels, this will point to a particular Python version, but Jupyter is designed to be much more general than this: Jupyter has dozens of available kernels for languages including Python 2, Python 3, Julia, R, Ruby, Haskell, and even C++ and Fortran!

The root of the issue is this: the shell environment is determined when the Jupyter notebook is launched, while the Python executable is determined by the kernel, and the two do not necessarily match.In other words, there is no guarantee that the python, pip, and conda in your $PATH will be compatible with the python executable used by the notebook.

In my current notebook environment, the two differ.This is why a simple !pip install or !conda install does not work: the commands install packages in the site-packages of the wrong Python installation.

So, in summary, the reason that installation of packages in the Jupyter notebook is fraught with difficulty is fundamentally that Jupyter's shell environment and Python kernel are mismatched, and that means that you have to do more than simply pip install or conda install to make things work.The exception is the special case where you run jupyter notebook from the same Python environment to which your kernel points; in that case the simple installation approach should work.

There is one tricky issue here: this approach will fail if your myenv environment does not have the ipykernel package installed, and probably also requires it to have a jupyter version compatible with that used to launch the notebook. So it's not a full solution to the problem by any means, but if Python kernels could be designed to do this sort of shell initialization by default, it would be far less confusing to users: !pip install and !conda install would simply work.

Even if the above changes to the stack are not possible or desirable, we could simplify the user experience somewhat by introducing %pip and %conda magic functions within the Jupyter notebook that detect the current kernel and make certain packages are installed in the correct location.

If a pip magic and conda magic similar to the above were added to Jupyter's default set of magic commands, I think it could go a long way toward solving the common problems that users have when trying to install Python packages for use with Jupyter notebooks.This approach is not without its own dangers, though: these magics are yet another layer of abstraction that, like all abstractions, will inevitably leak.But if they are implemented carefully, I think it would lead to a much nicer overall user experience.

After proposing some simple solutions that can be used today, I went into a detailed explanation of why these solutions are necessary: it comes down to the fact that in Jupyter, the kernel is disconnected from the shell.The kernel environment can be changed at runtime, while the shell environment is determined when the notebook is launched.The fact that a full explanation took so many words and touched so many concepts, I think, indicates a real usability issue for the Jupyter ecosystem, and so I proposed a few possible avenues that the community might adopt to try to streamline the experience for users.

I run an iPython Notebook server, and would like users to be able to download a pandas dataframe as a csv file so that they can use it in their own environment. There's no personal data, so if the solution involves writing the file at the server (which I can do) and then downloading that file, I'd be happy with that. 2ff7e9595c
